No....I'm prettty sure you can absolutely suck at boxing with 0 amateur experience and go pro if someone's dumb enough to be your manager and you can find a starving promoter who's crazy enough to take the liability.
That's interesting. I know in some countries you have to fight/spar for X amount of 3-minute rounds in front of a group of judges. They then gauge your offense, defense, stamina, etc., and decide if you're qualified for a pro license or not. Only if you pass do you pay the fees and receive your license.
basically it is that easy, plus medicals, blood tests, etc. But as far as boxing experience you can have nil. i think it's always good to get some amateur experience; at least 12-15 matches (ideally 30+). you can be novice for the first ten, which means that you're competing against other under ten match opponents. then get at least a few more as open class against guys with experience. just because you can KO guys with under ten fights doesn't mean anything in the big picture. guys with experience may not let you get away with what you did as a novice. also, boxing is a sport, so the amateur experience allows you to "experience" boxing; weigh-ins, taking direction from the referee/coaches, what to do when the OPPONENT gets knocked down, what to do when YOU get knocked down, competing in front of a crowd, etc, etc.
If its about the money than dont risk it, if its about love for the sport and want to progress then go and have fun, live to learn from your own experiences
